Where To Hang The Tie On Curtains How High Up Should I Hang The Tie Backs On These Curtains?

How high up should I hang the tie backs on these curtains? - where to hang the tie on curtains

The window is about 60 inches tall and 47 "wide. I have curtains at the window, and they vallace. The curtains are 84 products." I'm bound the way back to the hook is in the middle of the window and tie the new angle of the lower half down? It would be nice if the link is established on the windowsill in the city (the rule in this) do not seem to be funny. I have no photos.
